As they reach the top of a building they fight Vice Terhune. The protagonists journey to the 'City in the Sea' where they suspect the whole hunting network being operating from. Four heroes: mechanic and shaman Jack Tenrec, diplomat and explorer by profession Hannah Dundee, friend and engineer Mustapha Cairo, and mysterious Mess O'Bradovich, have decided to team up against the Black Marketeers. The continuous hunting process has made the dinosaurs violent and now they have started attacking villages and people. The story begins in the 26th century, when an ensemble gang called the Black Marketeers begin hunting the dinosaurs to serve their unknown purpose. Unless the game is continued within a countdown of 20 seconds, the baddie fires his gun, leading to a game over. When the player loses along the way, one of the big baddies holds a gun point-blank to the losing player's face in a first-person view, taunting the player with sayings such as 'Eat lead, baby!'. Players can also find and use various firearms, throwing weapons such as rocks and explosives, and melee weapons such as clubs.

Each character has two special moves including one that depletes a character's health upon contact with an enemy and when two or more players play together, they can trigger a team-attack. The players have access to several attacks. The game's titular dinosaurs make appearances as neutral characters that may attack both player characters and enemies.

There are four playable characters, each with their own strengths and weaknesses: Jack (balanced type), Hannah (skill type), Mustapha (speed type), and Mess (power type). Up to three players can play at once, guiding their selected characters through eight stages, battling various enemies and bosses.
